Depending on the nature of the ground, it may be necessary to cast a
bed of quick-setting concrete at the bottom of the hole to avoid subsid-
ence in future.
2. Place the foundation box in the hole, refer to the dimensions
provided in Figs. 6a and 6b.
The center of the pivot on the foundation box must be perfectly aligned
with the leaf’s axis of swing (Figs 6a and 6b).
3. Lay down a 1.5 inch diameter PVC tube through which a 4 core
electrical cable can pass. The tube must reach from the box to
the control unit (Fig. 7). Lay a second tube to drain rain water
from the box to the nearest drain (also Fig. 7).
4. Fix the box in place with a casting of concrete.

latter on the pivot in the foundation box, also inserting the ball
supplied (Fig. 8).
Note: grease both the pivot and the ball.
